Macromolecular delivery into skin using a hollow microneedle.
The objective of the present study was to obtain information to develop an effective delivery device regarding a sophisticated hollow microneedle array-patch system. Thus, the potential of hollow microneedles was investigated for enhancing the transdermal delivery of hydrophilic large molecular compounds, and the effect of variable parameters on drug release behavior was determined from skin. F...
متن کاملGene Silencing in Skin After Deposition of Self-Delivery siRNA With a Motorized Microneedle Array Device
Despite the development of potent siRNAs that effectively target genes responsible for skin disorders, translation to the clinic has been hampered by inefficient delivery through the stratum corneum barrier and into the live cells of the epidermis. Although hypodermic needles can be used to transport siRNA through the stratum corneum, this approach is limited by pain caused by the injection and...
متن کاملMicroneedle Enhanced Delivery of Cosmeceutically Relevant Peptides in Human Skin
Peptides and proteins play an important role in skin health and well-being. They are also found to contribute to skin aging and melanogenesis. Microneedles have been shown to substantially enhance skin penetration and may offer an effective means of peptide delivery enhancement. The aim of this investigation was to assess the influence of microneedles on the skin penetration of peptides using f...
متن کاملMicrofabricated Hollow Microneedle Array Using ICP Etcher
This paper presents a developed process for fabrication of hollow silicon microneedle arrays. The inner hollow hole and the fluidic reservoir are fabricated in deep reactive ion etching. The profile of outside needles is achieved by the developed fabrication process, which combined isotropic etching and anisotropic etching with inductively coupled plasma (ICP) etcher. Using the combination of S...
متن کاملInhibition of CD44 gene expression in human skin models, using self-delivery short interfering RNA administered by dissolvable microneedle arrays.
Treatment of skin disorders with short interfering RNA (siRNA)-based therapeutics requires the development of effective delivery methodologies that reach target cells in affected tissues. Successful delivery of functional siRNA to the epidermis requires (1) crossing the stratum corneum, (2) transfer across the keratinocyte membrane, followed by (3) incorporation into the RNA-induced silencing c...
